Abstract: 1493892 Pipe couplings FESTO-MASCHINENFABRIK GOTTLIEB STOLL 7 Jan 1975 [12 Jan 1974] 527/75 Heading F2G A disconnectible coupling of, e.g. plastics, steel or brass, for pipes of, e.g. plastics or rubber, has at one end a screw threaded connector 14 and at the other end a socket 12 adapted to receive a pipe end. The socket has a conical outer surface and is divided by a number of longitudinal slots 13 into flexible chuck segments 12a-12d (see section in Fig. 2) so that a securing ring 18 can be moved along the outer surface of the socket 12 to cause the chuck segments to clamp around the pipe end. The ring 18 may be secured in the clamping position by a projection 24 on the ring 18 engaging a groove 22 in the socket outer surface. Alternatively the latter may carry a projection to engage a groove in the ring 18, or the end zone of the socket outer surface may be less inclined tothe longitudinal axis to retain a ring 18 having a smooth inner surface. The inner surface of the socket 12 may carry toothing to improve the grip on the pipe end, and the latter may abut against an internal shoulder provided in the bore of the coupling beyond the end faces 13a to which the slots 13 extend.

Abstract: 1498829 Measuring angular position SOC D'ETUDES, RECHERCHES ET CONSTRUCTIONS ELECTRONIQUES 26 March 1975 [28 March 1974] 12711/75 Headings G1A and G1N (A) A digital angle coder comprises a fixed reading head TF, a reading head TMO relatively movable about a first axis through the angle to be coded, a member 5 rotatable at constant speed about an axis coincident with the first and carrying a plurality of marks adapted to be read by the reading heads which in co-operation therewith produce two series of read-mark signals, and angle-detector means for accumulating the time intervals between the signals of one series and the signals of the other series during one or more complete revolutions of the member 5. The heads TF, TMO may be magnetic reading heads and the marks recordings on a magnetic track. To compensate for any misalignment of the two axes a second movable reading head TMA is provided and the mean of the readings of the two heads T MO , T MA  is taken. In use, e.g. in a theodolite, the phase control circuit 15, Fig. 2 and origin setting 16 are activated and with the arm 6 in the first position the mean phase displacements read by circuits 23, 33 are stored in memories 24, 34. During rotation of the arm 6 to the second position the difference in numbers of pulses read by the fixed and moving heads are registered by the reversible counters 22 and 32, together with the sign of angular separation, and provide a coarse measurement of the angle. Pulses coincident in time are separated by anti-coincidence circuits 21, 31. A final mean phase displacement is then taken and subtractors 26, 36 supply the difference between this and the stored initial value to the circuit 18. Circuit 18 provides the mean of the fine measurements of angle from circuits 26, 36 and the mean of the coarse measurements from circuits 27, 37. In a second embodiment, utilizing optical methods, the fixed reading heads TFO, TF180 each comprise a photo-emission cell 420, e.g. an LED, a reflective grid 421 or 423, and a photo-receptive cell 422, e.g. a phototransistor. Coincidence between the marks on a grid with similar reflective marks 51 on a rotating disc 50 of low or zero reflectivity material causes a minimum in reflected light. For coarse measurements the auxiliary fixed head T 1  and the auxiliary moving head T2 read single marks 53, 54 respectively on the disc. The speed of the disc may be related to the frequency of the counter clock 1 or the clock may be enslaved to the disc speed which is maintained substantially constant.

Abstract: A drilling assembly includes a drilling tool having a shank and a drill bit at the leading end of the shank and having cutting edges.  The assembly further includes a collar adjustably and arrestably mounted on the shank, and an abutment member having a central passage into which the tool element is received at least during terminal phase of the drilling operation.  The collar has a convex contact surface, and the abutment member is formed with a depression bounded by a concave contact surface, the two contact surfaces sliding on one another when the tool element is pivoted to form an undercut hole in a support structure.  The abutment member abuts against a surface of the support structure around the open end of the hole, and is prevented from rotating with the tool element either by pins which penetrate into the support structure, or by a layer of friction-retarding material, such as rubber, interposed between the abutment member and the surface of the support structure.  The abutment member may have a tubular centering projection receivable in the open end of the hole in the support structure, The shank of the tool element has at least one helical recess for forwarding particulate material out of the open end of the hole, and the drill bit is formed with cutouts at the cutting edges in the regions of the turns of the helical recess.

Abstract: A system and method for removing colloidal suspensions or particles from a liquid, in particular tall oil soap particles from black liquor of a wood pulping process.  Black liquor is moved along a flow path from an upstream to a downstream zone.  First and second electrical conductors are respectively located in the upstream and downstream zones and means are provided for applying opposite electrical potentials to these conductors.  For removal of anionic colloids, the first conductor is made positive and the second conductor negative.  Thus, colloidal particles in the liquid having a relative potential opposite to the potential of the first conductor are attracted towards the first coductor as the liquid flows through the upstream zone, and some of the ions attached to some of these particles are stripped off by the electrical field, leaving these particles with a potential of the opposite polarity from particles not so affected.  The stripped colloidal particles attract other colloidal particles the charge of which has not been changed by stripping, thereby commencing the formation of agglomerates.  The particles are carried downstream by the liquid and through the field adjacent the second conductor, whereby the particles continue to agglomerate.  As a result of the continuous pressure from the flow, and of air introduced into the stream and a small amount of hydrogen and oxygen resulting from electrolysis of the water present, these agglomerates or globules are "washed off" the conductors into a separation vessel wherein there results a separation in the phases.  Removal of the soap or other separated materials in the vessel is accomplished by conventional means.  Improved agglomeration is achieved by also applying pulsating potentials to the conductors and by insulating both conductors so that, in addition to the electric field between them, there are separate electric fields between each of them and ground.

Abstract: An undersea cable plough for laying of a cable or conductor previously laid out on the bottom in a trench comprises a frame which can move forward along the bottom, a digging element and carrying elements for the cable or conductor. As the plough moves forward along the cable or conductor, the latter is led in a bend above the frame and down into the bottom of the trench. It is difficult to exactly follow the laid-out cable or conductor, and deviations from the correct direction of travel and jerking during movement results in skewed tensile stresses, which can damage or even break the cable or conductor. These inconveniences are avoided when the frame is comprised of a chassis for a controllable vehicle, which is provided with an element 16 for sensing the direction of the cable or conductor entering with the vehicle in the horizontal plane and with a mechanism controlled by the sensing element 16 for automatic influencing of the control equipment of the vehicle in such a way that the direction of movement of the vehicle is adjusted in the direction of the cable or conductor. <IMAGE>

Abstract: The invention is concerned with fractionation of proteins, in particular with fractionation of immunoglobulin containing solutions, such as blood plasma, by continuous flow electrophoresis. Hitherto, such solutions have been fractionated by ethanol precipitation methods (e.g. the Cohn Method). Such methods separate the IgG component of immunoglobulins but cannot separate the useful IgM component. In the invention, the solutions are fractionated by continuous flow electrophoresis at a pH of between 7 and 8.4 and an electrical conductivity of between 1 and 2 mScm-1, thereby giving rise to fractions containing particular combinations of immunoglobulin components (IgG, IgM, IgA, IgD and IgE) with potentially valuable properties.
